1. y = 4x + 9 ; m = 4 ; b = 9
the slope is 4 because there’s a pattern of +4 going down the function table in the “y” column
and b= 9 because at the number 0 on the x line has 9 in the y box
2. y = 3x - 1 ; m = 3 ; b = -1
basically the same thing as the first one just different numbers
Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
Answer:
x = √2, y = 2
Step-by-step explanation:
You know that the sides of an isosceles right triangle are equal in length, so ...
x = √2 . . . . same as the given side
You also know that the hypotenuse is √2 times as long as one side, so ...
y = √2·√2
y = 2
As per given by the question,
There are given that four point.
The point is,
Now,
From given point,
Then, the factor is,
Now, solve the above equation,
The factorial formd will be,
Now, find the value of "a" with the help of given point (0, -8).
So,
Puth the value of x =0, and y=-8 in above equation,
Then,
Then, a=2.
Now,
The value of a is 2.
And,
The polynomial in the factored form is,
Hence, the value of a is 2 and the polynomial in the factored form is,
Answer:
2
Step-by-step explanation:
2 units
